[0002] In the field of modern electronic manufacturing, the production scale of LED light strings continues to expand, and LED light string automatic placement machines have become key production equipment. As the demand for production efficiency continues to rise, the application of robotic arms in placement machines is becoming more and more extensive. Their high-speed operation can greatly increase the placement speed and meet the production capacity requirements of large-scale production.

[0003] The existing welding method usually adopts reflow soldering, in which solder paste is printed on the circuit board in advance. Through reflow soldering, the solder paste is melted at high temperature to form solder joints, and the light string and the circuit board are welded together. However, high temperature will be generated during the welding process, which may cause local deformation of the circuit board, affect the fixation of nearby light strings, and cause cold soldering or poor welding. In addition, the solder paste is easy to adhere to the suction cup, making the suction cup easy to be blocked, and it is easy to cause the light string to be unstable or due to impurities on the suction cup, the fixing position of the light string will be changed when the light string is sucked, causing the installation position to change.

[0004] In addition, when facing different types of lamp beads, traditional placement machines often require personnel to perform tedious suction cup replacement operations.

During this period, the inclined block 2 632 will squeeze the square rod 2 624, so that the square rod 3 626 moves and contacts the inclined block 3 524. The inclined block 3 524 is pressed to slide toward the side of the fixed seat 523 and separate from the tooth plate 526, releasing the limit between the two semicircular frames 1 520, and pulling the two semicircular frames 1 520 apart. The suction cup 527 releases the limit and falls from the inside of the two semicircular frames 1 520 to the ring frame 643. The personnel will put the square plate with the suction cup 527 The third square plate 642 is taken out from one side of the housing 610, and then the square plate 3 642 equipped with the suction cup 527 to be replaced is inserted into the housing 610 and positioned above the square plate 2 640. At this time, the L-shaped frame 630 will continue to move downward, so that the inclined block 1 631 contacts the square rod 1 620, and the square rod 3 626 is separated from the inclined block 2 632 and returns to the original position under the influence of the spring 3 625. After the square rod 1 620 is squeezed by the inclined block 1 631, the two semicircular frames 1 520 are gathered toward the middle, and the suction cup 527 placed in the ring frame 643 is plugged in. The toothed plate 526 is plugged in with the inclined block 3 524 to fix the two semicircular frames 1 520 together. A sealing is provided inside the semicircular frame 1 520. The parts can effectively prevent air leakage, the electromagnet 623 cancels the adsorption of the iron block 522, and the square rod 620 returns to the original position after being separated from the tooth groove 531, and the replacement is completed. The L-shaped frame 630 is provided to slide downward, so that the two semicircular frames 520 fixed together can be quickly separated, so that the replaced suction cup 527 is released from the limit and falls out. After replacing the new suction cup 527, the L-shaped frame 630 continues to move downward, so that the two semicircular frames 520 can be quickly gathered to the middle, and the suction cup 527 is plugged and sealed, which effectively improves the replacement efficiency of the suction cup 527, and does not require manual replacement by personnel, greatly reducing the replacement and downtime time, and improving the operation convenience and work efficiency.
